Samples will be selected by easy sampling method and then randomly divided into intervention and sham groups. In this study, individuals are divided into two groups using permutation blocks. In this method, the letter A represents a person in the intervention group and B represents a person in the sham group. Considering the quadruple block, we give AABB code 0, ABAB code 1, ABBA code 2, BAAB code 3, BBAA code 4 and BABA code 5. Then, using a table of random numbers, we randomly select the starting point, followed by 15 numbers in a row or column. Considering the order of the numbers in the table, we place the permutation for each number we encounter. For example, if the first three numbers in the random table are 2, 0 and 1, respectively, the order of receiving treatment by the first 12 people in the two groups, respectively. From left to right will be ABBAAABBABAB. Therefore, finally, by selecting fifteen numbers from the table, the method of allocating a total of 60 people to the two groups will be determined.
